A Goomba named Goomrisk managed to travel a few days into the future via a clock tower he discovered! However though, he soon had an unexpected visitor and learned that it's not really a happy future in the Mushroom Kingdom. The visitor fought Goomrisk as the Goomba requested.

Battle in the Future takes place just after The Flooded Tower, the latter of which should hopefully not be required to play in order to enjoy this. Play as Goomrisk, as he fights against two bosses in the game, starting with an amount of health that can be set somewhere from 1 to 6 (4 is the default amount). The graphics are 100% original in this game.
